The rules are very simple. Post a silly picture and the story behind it on your blog. Then add your link and become a follower. Visit other people's blog and follow the ones that you like.
If you have kids you know you have one of these pictures. This is the picture you get when your husband stands over you as you try to get a picture of your kids. Of course as he's trying to get their attention and smile, they are looking up at him not at the camera. Silly Daddy!
